產(chǎn)品特點(diǎn)：
本蝶閥主要由閥體、轉(zhuǎn)軸、閥板、閥座及驅(qū)動(dòng)機(jī)構(gòu)（手柄、蝸輪蝸桿、氣動(dòng)裝置或電動(dòng)裝置）等
組成，靠驅(qū)動(dòng)機(jī)構(gòu)帶動(dòng)轉(zhuǎn)軸及閥板旋轉(zhuǎn)以實(shí)現(xiàn)啟閉和控制流量的目的。其特點(diǎn)如下：
1、結(jié)構(gòu)簡(jiǎn)單、小巧輕便，運(yùn)輸、安裝、拆卸容易。
2、90°啟閉，開關(guān)迅速。操作扭矩小，省力輕巧。
3、密封性能好，使用壽命長(zhǎng)，可達(dá)到零泄漏。
4、選擇不同的零部件材質(zhì)，可適用于多種介質(zhì)。
5、流量特性近似于直線，調(diào)節(jié)性能好。
Produce Features:
A butterfly valve consists of body ,stem ,disc , actuator (manual actuator,worm-gear actuator , aerodynamic actuator or electric actuator) , and it can
implement the process for turning on turning off and regulating the flowby the circumrotation of stem and disc that is droved by actuators.
